I think my sprocket is getting a bit worn and need to be changed, but I’m looking for a second opinion. It doesn’t have the «shark fins» I’ve been reading about, but the sprocket fins look a bit thin and worn.
Would appreciate someone’s opinion it.
They’re definitely worn, you can see the valleys are getting elongated and the peaks are getting thinner. I always found it helpful to find a picture of a brand new sprocket to compare with.
If you can, it’s best to replace both front and rear sprockets and chain together.
Also, give your wheel a good inspection. It looks like cracks have formed near the visible bolts:
I don’t think that’s a crack, seems like a comstar style wheel, so that’s probably just where the two pieces meet.
Good eye! I wouldn’t have noticed. That seems problematic. Does that imply I should get new wheels?
I can’t say from the pictures but definitely give them a thorough inspection. Clean them until spotless then take a good look.
That trucker is definitely toast. Time for replacement.
Overdue, I would say.
Thank you! I guess I’ll change it asap then.
Way over due. Change both sprockets and chain.
That’s done for. Time to change both gears nd the chain.
